switch power wire?

[dizzlenizzle]

i just bought a DEH-P3500 pioneer stereo and the manual doesnt come with a wire diagram. I want to hook up rear box speakers that are powered by an amp but i cant find the switch power wire that will make the amp turn on only when the car is turned on. Does anyone know what color the wire is or where i could find this wire?

the remote turn-on wire is usually blue with a white band. using this wire, the amp will turn on only when your head unit is turned on. however, in your case, it seems that you want to amp to turn on when the car is running. i think you can use the ignition wire, color is red, to have the amp turn on when the ignition is on. your best bet is to use the remote turn-on wire from you head unit.
